None that I know of for Himalayan ferns, unfortunately. That's why I'm a bit cautious about naming them - although ferns often have very wide distributions (the spores can blow long distances), it is possible that some may just be close relatives of the species I named, rather than exactly the same. With a few, I was able to find references to their occurring naturally in the Himalaya as well as here (NW Europe), so with those I am more confident.

Resin, they are close relatives. NW Europe, yes that chain also comes and meets the Himalayas and the Hindu Kush at Pamirs. There is absolute silence on Himalayan ferns on the net. Except for the Chinese the rest, including us?

Yes, rather unfortunate! The Flora of Pakistanhttp://www.tropicos.org/Project/Pakistan is a good reference, but is not yet complete, and ferns are in the part not yet done. Maybe it will become available soon. I see there is a contact address on their web page (scroll to near the end, just above the references) - maybe it might be worth asking them to put you in contact with whoever is working on the ferns volume?
